is it suitable to use JBoss Messaging to notify events to a large number of swing clients distributed across the globe? if not what is the suitable architecture for that?

[JBoss Seam] - Asynchronous call before App Startup

by damatrix

Hi, I'm using JBoss Seam 1.2.1.GA. I've been trying to start an asynchronous process that send out notifications of an event in emaisl immediately the application starts up. This event may have already been configured during a previous run of the application. The asyncrhronuous method also needs to have access to an EntityManager to read the details of the event and to a facelet-configured email template. The problem is i don't know how to automatically invoke the asynchronous method before the first user even logs in and what scope to outject the list of recepients and data so that the email template can send it. I've tried @Startup and @Scope(APPLICATION) but the contexts are not configured at that stage so i get a null pointer. Any ideas?

[JBoss Seam] - Re: Validation and selectOneMenu question

by damianharvey

1. Other than setting required="true" I don't think that there's much else that you can do. 2. Are you reRendering your selectOneMenu after the ajax4jsf call?

[Performance Tuning] - Threading scalability concerns using Linux ??

by jbride

Hello, The JBoss for Administrators course (RH336) mentions the following: Thread scalability is your most important concern Java applications are heavily threaded Burden on the OS is on the efficiency and scalability of thread scheduling Thread scalability on Linux has been an issue I'm wondering whether threading scalability on Linux is still a concern? Anybody know of any recent articles/discussions/stress test results on this topic involving JBoss (> 4.0.5 ), RHEL 5 and Sun JDK1.5 ?? Thank you, Jeff View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4067424#4067424 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4067424

[JBoss Seam] - Re: How bad is unused conversations?

by jcg3

Couldn't one use the conversationList object, inject it into your java class, and iterate through the conversations -- destroy'ing the ones that are no longer needed? Not necessarily elegant, but if propagation="end" doesn't actually end the conversation, it seems like an alternative worth exploring.

This is what I have: | <h:selectOneMenu id="inputMethods" value="#{dataEntryHome.instance.inputMethodType}" required="true"> | <s:selectItems value="#{enumeratedTypesList.resultList}" var="enumeratedTypes" | label="#{enumeratedTypes.name}" | noSelectionLabel="Select an InputMethodType..."/> | <s:convertEntity /> | </h:selectOneMenu> | Am I missing a jar file?

[JBoss Messaging] - Detected failure on control connection

by bob_walker99

Can someone offer an explanation of what exactly is happening when I get this error: org.jboss.remoting.transport.bisocket.BisocketServerInvoker$ControlMonitorTimerTask@20dbb1: detected failure on control connection Thread[control: S ocket[addr=/127.0.0.1,port=3160,localport=2999],5,main]: requesting new control connection I'm seeing it a lot, but the only references I can find on the forums are these: http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4055249#4055249 http://jira.jboss.org/jira/browse/JBREM-725 These don't seem to be the same case - I'm not seeing the NPE, and it isn't a server/client restart issue for me. I'm using AS 4.2.0 with JBM 1.4.0 CR1, (but it also happened in 1.3.0 GA and I'm currently running my tests on an XP box with JDK 1.6.0_02. I replaced jboss remoting with the 2.2.0 SP1 version, to no avail. I can't recreate it consistently in a test case (but it does happen intermittently in the tests I've written) but it happens a lot in (what would be) my production code (if it worked..). If it is something I am doing incorrectly, I need to understand what this is, but I'm at a loss where to look. Help? Sorry if this belongs on the remoting forums, let me know and I'll repost if necessary.

[Messaging, JMS & JBossMQ] - Re: Messages always persistent in Topic

by fljmayer

To the contrary, several people here looked pretty hard. But I have to say, I like your style. Why bother with providing information in a forum when you can simply insult people instead? But seriously: I you can't answer my questions, please don't reply to my posts in the future.

[JBoss Portal] - Re: Memory Leak

by bdaw

Its quite well known issue that when you hot redeploy bigger webapp dozen of times you end up with out of memory exception. As far as I remember its related to garbage collection issues with Class class and its more related to Java than AS. Normaly - never use hot redeployment in production and increase heap size during development. Still I'm not saying there can't be any other bug causing memory leak.
